- Whole floors of tired en suites
- Failed floor-level joints in accessible wet rooms
- Split sealant around staff kitchen worktops and sinks
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Tell cleaning staff when each room can be used
- Leave squeegees in busy showers
- Use mild cleaners on sealant, not bleach or abrasives
- Act on lifting sealant before it leaks
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Why deal with it now?
Sealant is easy to forget until an audit or inspection is due. Booking it in good time leaves room for the cure time before the visit, without a last-minute rush. Around Lake End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Why us?
- Sealant colour chosen to suit
- 20+ years of sealant experience
- An ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet
Surface by surface
Office washrooms & kitchens
Kitchen and tea point joints are degreased and resealed, using a food-safe sealant by sinks where it’s needed.
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so joints are sealed with anti-fungal sanitary silicone.
How it works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a morning for a small washroom, and a planned programme for bigger sites in most cases. In a small place like Lake End, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
Getting a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For landlords with property near Burnham station, sealant work can be quoted for a single flat or a whole portfolio. For buildings such as Church of St James, its kitchen and washroom sealant needs looking after like anywhere else.
